Fig. 3.

Learning time course in the horizontal and sagittal conditions during rotation phase. A and B: average reach direction for the right (A; red) and left (B; blue) limb in the horizontal condition during baseline (blocks 1–8) and rotation phase (blocks 9–63). The green trace represents the average amount of explicit learning measured from the verbally reported aiming direction. The purple trace characterizes the average implicit learning computed from the difference between the actual reach direction and reported aiming location. C and D: average reach direction for the right (C; red) and left (D; blue) limb in the sagittal condition during baseline (blocks 1–8) and rotation phase (blocks 9–63). Green and purple traces represent the average amount of explicit and implicit learning, respectively. Each block represents the average of 4 trials (Blks/4 trials), and shading represents SE of the mean.
